Crysis

I finally was able to get Crysis thanks to the Steam sale, finally got all of them downloaded, and now every single one doesn't work.

All 3 just tell me "Crysis has stopped working" and exits. I've searched all over the internet and have found no solution. Deleting the save files does nothing. I tired compatibility mode and run as admin and nothing at all works.

Also, after reading through here, everyone has been posting the same link to some thread that supposedly fixes everything but it's always invalid request. I would greatly appreciate some help with this.
